    <div class="description">
        <div class="ng-window-page"><p>A reference to the browser's <code>window</code> object. While
            <code>window</code>
            is globally available in JavaScript, it causes testability problems, because
            it is a global variable. In angular we always refer to it through the
            <code>$window</code> service, so it may be overriden, removed or mocked for testing.</p>

            <p>Expressions, like the one defined for the <code>ngClick</code> directive in the example
                below, are evaluated with respect to the current scope. Therefore, there is
                no risk of inadvertently coding in a dependency on a global value in such an
                expression.</p></div>
